### 1/5 — Still does not support the tri-color 2.13” display

*2026-05-25*

Even with this latest update it does not support the 2.13inch NFC-Powered e-Paper (G) tri-color display

### 3/5 — No support for the 2.13” Color tag

*2026-02-18*

Works for 1.54” but 2.13” is not listed in the app

### 1/5 — Doesn’t work since update

*2026-01-04*

Sits at 1%

### 3/5 — Issue with 2.7in screens

*2025-11-25*

When loading images onto 2.7in screens (SKU:18136, Part No.:2.7inch NFC-Powered e-Paper Module) the bottom few rows of pixels end up getting copied or rewritten on the top row. It is almost as if the image has been scrolled within the screen and wrapped around.

This is the case with all 4 of my 2.7in displays but not my 2.9in (SKU:17746
Part, No.:2.9inch NFC-Powered e-Paper).

Other than this issue with 2.7in screens the app works well and is quite simple. If this is fixed I will update my review accordingly.

### 4/5 — A little buggy but it works

*2025-08-04*

Some small issues with some fonts, but it works to update my Waveshare 2.7” NFC-powered ePaper.

### 1/5 — Most recent update killed it

*2025-05-11*

It used to fail every now and then. Usually moving my phone a little and trying again would fix the problem. After the most recent update it fails 100% of the time. It’s like it just stops updating the keychain picture part way through the process and I’m left with a very faint image that is impossible to see. And the red color is not there at all.

### 5/5 — Works well enough

*2024-11-27*

I was able to easily transfer a picture to my NFC E-Ink keychain. Cropping, scaling and dithering the image all worked well. I’m pleasantly surprised by the quality.

### 5/5 — Works great for uploading images

*2024-11-13*

Smooth experience

### 1/5 — Landscape only

*2024-11-01*

Why no way to display images in portrait? Ridiculous.

### 1/5 — Only works 10% of the time

*2024-09-29*

It’s per much junk. Once in a while it works great and draws a very good image however most of the time the app stops while it is still drawing the image and it doesn’t finish the image. It’s pretty much no good.
